AV8R mentioned LPS#2 man, that I think is the best invention
since peanut butter. Up north where they use salt on highways in
winter,LPS keeps corrosion from forming on brass light sockets on cars,
also disperses moisture from any metal or plastic once you spray it
on.also good on battery cables.
If I store guns in cases I run a patch with it threw my barrels.
The man that demonstrated the stuff to me took a large switch
that would flash several flood lights, sprayed it with LPS#2 and
dropped it in a 5 gal water pale while plugged in .
that sold me on LPS.

It also smells a little better than Hoppes Potion #9
Rain X I think has glycol and some alchol if I remember right.
